Application filed May 13. 1913. Serial No 767.314.

[u all how '1'! may 'o/lf-zrrli. the metal to afi'ord the desired grip Be it knmvn that I. do. .rn .l-"uuo lViXon, of Ilamniondsport. in the county of SURF hen, in the State of Xcw York, have invented new and useful improvements in Metallic Phil-faring of which the following, taken in 5 connection with the acronn'ianying draw-- lugs, is a full, clear. and exact description.

This invention relates to certain improvements in pavements and refers more par ticularly to metallic surfacing for roadheds, sidewalks and other pavements having a. cement. concrete or equivalent celncntitious 1 foundation.

I am aware that many forms of metal sur facing have been heretofore proposed for these purpcses. but so far as i am aware no adequate provision has been made to prevent slipping or skidding of horses and vehicles. and the primary objectof my present invention is to provide a sheet metal road snrfacii'ig laid upon a bed or foundation of cement or concrete in such a manner that it will afford ample gripping; elements for horses feet and vehicle wheels to prevent slipping or skidding, without rendering such surface undulatory or rough so that pedestrians horses and vehicles may travel over the same with perfect safely and with out inconvenience. 7

Another object is to provide means where by the metal plates may be accurately and expeditiously laid in sequence in relatively of a previously prepared bed or foundation 1 of cement or con rete while still in a par l tially green or plastic state, with the assoc anc, that when so hid it will he perma-l ncntly held in position by the cement when the latter is seasoned or set.

In other words, I have sought to provide the meeting ends of the plates with integral interlocking members capable of being pin l inancntly' interlocked by the simple operation of placing the plates consecutively in bed. and also to acconn'ilish the -17Q1'I\l:llu3lllsecnrement of said plates to .the surface of l the cementitious bed by providing such l plates with integral flaring petulant tlaneos or projections stamped or pressed from the b l aperi arcs of relative y hall area syininetrically distributed thr= I out the area of each plate and left open through the thickness of I 1 producing a erred to.

l'lthcr chic" in the 'lollovvm de; tion:

in the drawiu Figure .l is a perspective view of a portion of a roadbed or pavement equipped with my improved metal surfacwill, be brought out mg. Fin. 2 13-; an enlarged transverse sectional view of the same roadbed 1g. 3 is an enlarged longitudinal sectional View of a l'ran'nn-nt of the same pavement, showing the manner of interlocking the consecutively arranged plates. Figs. l and 5 are perspeclive views of portions of the interlocking ends of adjacent plates.

'lhia pavement comprises a series of sheet metal plates- ---l laid in sequence, edge to edge, upon t surface of a previously prepared bed or foundation 2 of concrete, while said surface still in a more or less green or plastic condition, said plates having their meeting edges provided rospectively with slots ---3 and tongues --4lspaced uniform distances apart so thatthe tongues of one plate may readily enter the slots of the adjacent plate for establishing a positive interlocking connection between said plates against relative movement.

The tongues of one-plate and adjacent; longitudinal edge of the other plate are depressed to a plane beneath that of their re- I extend under the adjacent plate when interlocked therewith while the edge of the other plate underlies the edge of-thc one having v the tongues. thereby bringing the surfaces of tl adjacent plates in the same horizontal plane and affording a close joint and sub stantially conti'inzous surface without. appreciable break. Each plate provided with a plnralit: of rows of perforations -5- preferably elongated in one direction and having diverging or flaring end walls formed by cutting and depressing integralv portions of the plate downwardly, thereby corresponding number of pendant ribs or flanges 6- having similar flaring or divergent ends which are embeddcd. in the concrete as the plates are pro- I Ql'dSlVtlV placed in operative position upon main body. thereby tornnng :ori'e;-poinlin i the surface of the ceinentitions bed, The form of these ribs is shown more clearly in Fig. 2 and the object of flaring the ends is to produce a firm interlocking grip with the concrete or cement. That is the flaring ribs afford a dove-tailed interlocking connection with the concrete when embedded therein, thereby rigidly holdingthe plates in position against upward displacement when the concrete is set without additional or extra fastening means. By this method the metal surfacing is completed as the plates are progressively laid upon the surface of the eoncrete, leaving the openings -5 in the metallic surfacing the full depth thereof and, inasmuch as these openings are in close juxta osition and relatively small as com pare with the area of the plates, it is evident that they afford am Is rip for horses feet and also prevent s id ing of vehicle wheels, thevplates being usually cut in such lengths as to reach from curb to curb although it is clearly evident that they may be made in smaller sections, i necessary, without departing from the spirit of my invention or in any way reducing the efliciency or smoothness of the metal surfacing.

It will be seen from the foregoing description that the important features of my invention are the simple interlocking'connectherefor consisting of plates arran d edge to edge and havin their meeting e gee provided with interocking connections, said plates being also provlded with pendant projections embedded in the concrete.

A pavement comprising a bed of cementitious materialand metal plates arranged edge to edge on the surface of said bed, the ad acent edges of the plates being provided respectively with a series of apertures and tongues passed through said apertures whereby the plates are locked to each other.

3. A pavement comprising a bed of cementitious material and a metal surfacing therefor consisting of a series of sheet metal plates arranged edge to edge and having their meeting edges provided with interlocking connections, each plate having a series of integral pendant ribs stamped therefrom formin a corresponding number of apertures, t e ribs bemgembedded in the concrete leaving the apertures open the full depth of the plates.

4. A pavement comprisin a bed of cementitious material, metal p ates applied to the surface of said material and each provided with a series of apertures having flaring ends, said plates being also provided with pendant ribs integral with the shorter sides of the apertures and having flaring ends embedded in the concrete leavin the apertures open the full depth of the p ates.

In witness whereof .l have hereunto set my hand this 5th day of May 1913.
